OpenAI to acquire Statsig; Founder Vijaye Raji to join as CTO of Applications unit
Raji will lead product engineering for ChatGPT and Codex, with responsibilities spanning core systems and product lines, including infrastructure and integrity, OpenAI said.
OpenAI on Tuesday said it will acquire experimentation-platform company Statsig and appoint its founder, Vijaye Raji, as Chief Technology Officer of its Applications unit, reporting to Applications CEO Fidji Simo, as the company scales ChatGPT and other products for consumers and businesses.
He will lead product engineering for ChatGPT and Codex, with responsibilities spanning core systems and product lines, including infrastructure and Integrity, OpenAI said.
“Vijaye has a remarkable record of building new consumer and B2B products and systems at scale. He’s joining at a time when our models are opening entirely new ways to build, and his leadership will help turn that progress into safe applications that empower people with many new tools to improve their lives, help companies increase their impact, and allow developers to build faster and better products,” said Fidji Simo, CEO of Applications, OpenAI.
Raji is a Pondicherry University alumnus who graduated with a Bachelor of Engineering in July 1999. He founded Statsig after a decade at Meta (formerly Facebook), where he most recently served as VP and Head of Entertainment from April 2019 to February 2021.
After the deal closes, Statsig employees will be onboarded to OpenAI. Meanwhile, Statsig will continue to operate independently from its Seattle office, with a measured approach to integration to ensure continuity for existing customers. The closing is subject to customary conditions, including regulatory approval.
OpenAI described its Applications unit as the group responsible for turning frontier AI research into safe, intuitive tools used at a global scale—work that depends on strong engineering systems, rapid iteration, and a long-term focus on quality and reliability.
The Sam Altman-led AI giant said Statsig’s platform—used for A/B testing, feature flagging, and real-time decisioning by companies, including OpenAI—has already played a central role in how it ships and learns quickly.
Bringing the technology in-house is intended to accelerate experimentation across applications and improve responsiveness in user experiences.
Raji said, “Joining OpenAI as CTO of Applications is an extraordinary opportunity to bring my experience scaling consumer and enterprise products to a mission I deeply believe in: advancing AI in ways that are capable of solving hard problems, reliable, and truly beneficial to people everywhere. The journey with Statsig has been deeply gratifying, leading me to this moment and giving me conviction that we will continue helping teams ship better software every day.”
